Subject: [RFC PATCH 2/4] usb: chipidea: ci_hdrc_imx: Introduce CI_HDRC_DUAL_ROLE_NOT_OTG for Vybrid

The Vybrid SoC has a dual role device which can be configured to
act as a host or device through firmware interface, but, it is
not a true OTG controller.

Use the CI_HDRC_DUAL_ROLE_NOT_OTG in the platform flag, introduce
a new platform data structure for Vybrid and match on the compatible
string fsl,vf610-usb instead of the earlier fsl,imx27-usb.
